This paper summarizes Professor DING Ying's clinical experience in the treatment of systemic lupus erythematosus （SLE） through differentiation of three states， yin fire， latent fire， and fire toxin. It is proposed that fire pathogenic factors constitute a key pathological element running throughout the entire disease course of SLE. The evolution of its pathogenesis centers on these three states， spleen-kidney deficiency with the initial emergence of yin fire as the onset of disease， damage to yin by medicinal toxicity with internal blazing of latent fire as the driver of disease progression， and the interlocking of blood stasis and heat with intense scorching by fire toxin as the critical factor leading to severe and life-threatening conditions. Corresponding to these three stages， targeted prescriptions are formulated， Jiuwei Yishen Formulation （九味益肾方） to tonify the spleen and kidney， raise yang， and disperse fire； Ziyin Xiehuo Decoction （滋阴泄火汤） to nourish yin and fluids while clearing latent fire； and Santeng Changluo Jiedu Decoction （三藤畅络解毒汤） to dispel blood stasis， unblock the collaterals， detoxify， and restrain fire. This staged and integrated therapeutic strategy aims to address both root and branch and to achieve overall regulation， providing valuable guidance for the clinical differentiation and treatment of SLE.

This paper　explored the disease mechanism of autism spectrum disorders （ASD） from the perspectives of “vital activity” and “qi configuration”， and it is believed that “vital activity” represents the internal regulatory mechanisms of the human body， while “qi configuration” represents the ability of the body to communicate and adapt to the external environment. Abnormal genetic factors lead to the extinction of vital activity in children with ASD， resulting in increased susceptibility to ASD. Environmental instability leads to the solitary qi configuration in ASD， triggering and exacerbating the manifestations of ASD on the basis of genetic susceptibility. In addition， epigenetic mechanisms also play an important role in the pathogenesis of ASD. Imbalances in vital activity and disruptions in qi configuration result in failure in qi transformation of zang-fu organs， with abnormal symptoms manifested through the five orifices. It is proposed that the treatment of ASD should aim to achieve a harmonious interaction between “vital activity” and “qi configuration” to accelerate the recovery of affected children.

OBJECTIVE To prepare curcumin /berberine co -loaded self -microemulsion drug delivery system （CUR/BER- SMEDDS）and evaluate its physicochemical properties and in vitro anti-tumor effects . METHODS Using CUR and BER as model drug，based on the screening of the type of oil phase ，emulsifier，co emulsifier and their mass ratio ，the formulation of CUR/BER - SMEDDS were optimized by central composite design -response surface methodology ，taking particle size and drug loading as evaluation parameters ，with the mass percentage of oil phase and the mass ratio of emulsifier to co emulsifier as factors ，and verification test was conducted . CUR/BER-SMEDDS prepared by optimized formulation were evaluated in terms of physicochemical properties，in vitro dissolution and in vitro anti-tumor effects . RESULTS The optimized formulation of CUR/BER -SMEDDS included that the oil phase was medium chain triglyceride （30.97%），the emulsifier was polyoxyl 40 hydrogenated castor oil （46.77%），the co emulsifier was polyethylene glycol 400（22.26%），and the mass ratio of emulsifier to co emulsifier was 2.10∶1. The validation experiments showed that mean particle size of CUR/BER -SMEDDS was（58.90±5.41）nm，the average drug loading was（94.94±3.87）mg/g，and the relative deviations from the predicted values were －2.90% and －0.14%，respectively. The CUR/ BER-SMEDDS prepared by optimal formulation was light yellow ，clear and transparent liquid after emulsified with water ，and its particles were spherical . The results of dissolution test in vitro showed that after SMEDDS was made ，the cumulative dissolution of CUR in artificial intestinal fluid and artificial gastric fluid and that of BER in artificial intestinal fluid were significantly higher than those of its raw material . Results of in vitro anti-tumor experiment showed that IC 50 values of CUR/BER -SMEDDS for PC -3 cells and DU -145 cells were （17.38±2.84）and（20.89±1.26）μmol/L，which were all lower than those of CUR and EBR significantly （P＜0.05）.CONCLUSIONS The optimized prepar ation process of CUR/BER -SMEDDS is stable and feasible . The drug release of CUR/BER-SMEDDS is more complete than that of single drug，and has stronger anti -prostate cancer effect in vitro .
